A Maryland audit on minority business participation at casinos has found that data is incomplete.

The audit by the state's Office of Legislative Audits released Tuesday found data provided by licensees was accurate and published by the Maryland Lottery and Gaming Control Commission in 2012.

But the audit says construction expenditure data for two licensees for all of calendar year 2012 was not included. The audit says that's because the Governor's Office of Minority Affairs did not obtain comprehensive data from the licensees.

The audit also says the commission had not established procedures to verify the data compiled and reported by the minority affairs office.

The gaming commission and the minority affairs office say they have implemented changes as a result of prior audit to better ensure completeness and accuracy.
